For integer n.
If n divided by 3 has no remainder, divide n by three.
If n divided by 3 has remainder 1, n = 2n+1
If n divided by 3 has remainder 2, n = 3n+3

It's math. It's just fucking math. You can't deny math. There isn't enough uranium or any other non-renewable resources on the planet to power it for much longer at the rate it's being used. The fact that you can't even comprehend something as simple as this means you're a complete moron, and there is no point debating you.

>There's even games that specialize in asteroid mining
You're actually serious? There's a game where you have magic and can fight dragons, too. Are you going to suggest next that magic and dragons are also possible? What a joke.

You're obviously Jewish. Yes it's that easy to see. That being so there's point in talking to you.

Wow.

You've been so thoroughly outdone that you reached deep, deep into your mind and came up with your last argument

Anti-semetism and name-calling.

Wow. Dude you're a fucking genius. Hey EVERYONE come over and take a look at how much of a genius this guy is. When you've been made to look like a complete moron, just call him a Jew and you won the argument!

God, I fucking love imageboards.

Here's a different idea about Gnome. What if the whole thing is being damaged by commercial interest? What if people are paid off to trash the whole thing? Some illumination of the idea.

I noticed that every time Linux gets a good GUI system that's almost there it runs off the rails and turns to shit. If there was a good serious stable GUI for Linux I expect it could rapidly replace windows. It can now but not without a lot of trouble.

Some examples. There was a GUI desktop called Enlightenment. It was way ahead of even windows. Very good stuff. It had some bugs but the basics were there and then all of a sudden they rewrite the whole damn thing and make no progress for many, many years.

Say you are Microsoft and you see this kick ass program full of features that would not come up until Apple does some of the same stuff later. It uses minimal resources and is fast on lightweight computers, it's free and it threatens to derail your multi-billion dollar profit stream.. OH SHIT. So you get a lawyer and he contacts the few main contributors to this desktop and they sign non-disclosure agreements. They offer them say a million a piece for maybe the top 5 guys to stall this thing for 8 years or so.

Another. Gnome is getting really good. Most things falling into place and it's rapidly becoming the desktop of choice. If it keeps going like it was then it could cause a network effect and draw in mass support and WHOOPS they rewrite the whole thing, take away tons of options and turn it into some freakish tablet interface that everyone hates. Whole thing stalls for for years and years while they screw everything up. Eventually causing forks into several different desktop GUI systems. Hmm...

Another and this is the one that made me come up with this idea because it was so damn freakishly absurd. PC-BSD. I was really liking this. It was extremely close to being a plug and play go to operating system with excellent file system. All of the unix tamed so you could use it like a normal system and then Shazam, all of a sudden they change the name to some nonsense, TrueOS(what the hell does that mean), then another name change to Trident OS and then immediately after that they completely stop using BSD as their base and switch to Void Linux. WHAT? I mean who ever heard of that? Why would you work for over a decade on FreeBSD base then all of a sudden switch to some obscure Linux? Total bafflement. Makes no sense at all. Their excuse was that FreeBSD was not moving fast enough but FreeBSD had all it needed to be a great desktop. They even wrote a great window manager and LOTS of supporting software and then abandoned it.

Now I can't prove anything but this last switch with PC-BSD really made me think that they just paid some people off and torpedoed alternate OS development. It was so bizarre. I mean if they were going to move to Linux why not Debian for which t Message too long. Click here to view the full text.

This is a hilariously naive vision of the situation, and you've hinged your entire point on this idea.

First, the interface is just one of the reasons why someone might choose to use an operating system over another. The software ecosystem is certainly much more important, as is the hardware compatibility. Windows wins over Linux on both these fronts, although there's a few specialized tools here and there that really do only work on Linux.

Second, there's never really been a desktop environment for Linux that was objectively better than Windows'. Microsoft just has deeper pockets than any DE organization and can afford to spend as much as it wants on GUI research.

Finally, if someone has bought into a platform, it would not be enough for a competitor's GUI to be better to get them to switch. It would have to be significantly better, perhaps even revolutionary, to justify the cost of migrating to an unfamiliar platform.

Your only emphasizing my point. Enlightenment was not finished and went onto a multi-year halt where everything stopped. Enlightenment had many features that Windows took many years to implement. It was also smaller and faster. With more work maybe it would have crushed the bugs it had. Instead it came to a halt.

Gnome instead of refining what they had discombobulated into a totally different desktop. Removing features and totally changing the way it worked.

They didn't die they were murdered.

I heard that such industrial electric motors used in machine tools and heavy metal industry

For example, if you use frequency converter in your industrial enterprise I suggest you to check https://eltra-trade.com/catalog/abb-acs880 drive where you can find energyefficient and powerful drives. AS you know Semiconductor devices consist of a power part made on transistors or thyristors, and a control circuit based on microcontrollers. This electrical equipment is suitable for three-phase and single-phase drives of any purpose.

I like the way you think.

To sanitize clothing use a solution of at least 71 percent pure isopropyl. Put it in a spray misting bottle with a fine mister.

It is better to err on the side of caution, and go over 70 percent if you don't chemistry well.

ax^2+bx+c=0

So you can see everything is on one side and on the other we got 0 so think about this like "where is the function equal to zero [f(x)=0]"
Look at the picture, you can see that there are 3 possibilities; 2 points at which function is equal to 0, 1 point (only the tip of parabola) or there are none. We solve it a bit differently in my country (I think in easier to understand form) so I'll show you how we are thought. First you look at 'a', a can't be equal to 0 (it would be linear equation if a=0), ok 'a' isn't 0 , that means we got a parabola, we can determine whether there are 2, 1 or 0 intersections with the X axis by calculating Δ (capital greek delta)
Δ=b^2 - 4ac
ok so you calculated the Δ, if the Δ<0 that means no intersections with X axis, Δ=0 1 intersection with X axis (the tip) and if Δ>0 we got 2 intersections with the X axis. When you got Δ<0 the equation can't be solved (no points at which function is equal to 0), if Δ=0 (only the tip is touching the X axis) you calculate the X coordinate of the tip, formula for that is (-b)/2a; if Δ>0 we must do a little bit more to solve the equation, because for Δ>0 there are 2 points touching the x axis, we use 2 formulas (-b+√Δ)/(2a) and (-b-√Δ)/(2a) similar to standard quadratic formula.

let's do some examples then

x^2 + 2x + 1 = 0

1) Δ= b^2 - 4ac = 4 - 4*1*1 = 0
2) Δ = 0 so we use formula for the X coordinate of the tip, (-b)/2a = (-2)/(2*1) = (-2)/2 = -1
3) f(x) = 0 if x = 1

sorry, in the 1st example I wrote (f(x)=0 when x=1)
x=-1

Whoa, I just saw this the other day while I was looking for a comment I made in the seventh page.

Dude, you're responding to a question from three years ago. I'm sure OP has since learned what a quadratic equation is, or they don't care anymore.

Your method seems a tad too complex for my liking. Why do you think it's better than simply remembering
x = (-b (+/-)sqrt(b^2 - 4*a*c))/(2*a)
? That's a single formula that solves any quadratic equation in a single step.
